This is most likely negligence, but I typically have 3-4 VMs open. One is for hotfixes, one for next feature branch, one for secondary project, one for another experiment. It keeps things really clean from a deploy point of view and reduces the cost of context switching greatly. This is VMware stuff running on Windows 7. I'd love to hear more ideas. All 16GB of my random is always in use.
